PSLE Grading System: How AL Scores Shape Secondary School Posting

Singapore's Primary School Leaving Examination (PSLE) no longer uses the T-score. Since 2021, the Ministry of Education (MOE) replaced it with Achievement Level (AL) bands — a grading system that groups raw marks into eight broad bands instead of ranking students against one another. For parents of Primary 5 and Primary 6 students, understanding how AL scores translate into secondary school options is the single most important piece of the posting puzzle.

The shift from T-score to AL scoring was designed to reduce excessive fine differentiation among students and encourage a focus on individual learning progress rather than competition. Under the current system, each of the four PSLE subjects — English, Mathematics, Science, and Mother Tongue — receives an AL score from 1 (best) to 8, and your child's total PSLE Score is simply the sum of these four numbers. The lower the total, the stronger the result: a perfect score is 4, while the highest possible total is 32.

The PSLE Achievement Level (AL) grading system is a criterion-referenced scoring framework that maps a student's raw examination marks to one of eight achievement bands per subject, producing a total PSLE Score used for secondary school posting. Unlike the old T-score, which ranked students on a bell curve relative to their cohort, the AL system evaluates each child against fixed performance standards — meaning your child's score does not depend on how well others performed in the same year.

How the PSLE AL Scoring Bands Work

Each subject's raw mark falls into one of eight AL bands. The band boundaries are fixed by MOE and do not change from year to year, so parents can plan with a known target. Here is how the bands map to marks:

• AL1: 90 marks and above
• AL2: 85 to 89 marks
• AL3: 80 to 84 marks
• AL4: 75 to 79 marks
• AL5: 65 to 74 marks
• AL6: 45 to 64 marks
• AL7: 20 to 44 marks
• AL8: Below 20 marks

A student who scores 88 in English (AL2), 76 in Math (AL4), 82 in Science (AL3), and 71 in Mother Tongue (AL5) would have a total PSLE Score of 2 + 4 + 3 + 5 = 14. This total is the number that secondary schools use to determine admission, along with the student's choice order and any tie-breakers such as citizenship and school proximity.

What counts as a competitive PSLE Score?

A PSLE Score between 4 and 8 is generally considered excellent and places a student in strong contention for Integrated Programme (IP) schools and top-tier secondary schools. Scores between 9 and 14 are solid and open doors to many reputable Express-stream schools. A score from 15 to 20 typically qualifies a student for the Express stream at neighbourhood schools, while scores from 21 to 25 align with the Normal (Academic) stream. Scores of 26 to 30, with AL7 or better in English and Mathematics, correspond to Normal (Technical). These are broad indicators — actual cut-off points fluctuate slightly each year based on cohort demand and school popularity.

Secondary School Posting Under the AL System

Secondary school posting is determined by the PSLE Score first, then by tie-breakers in this order: Singapore citizenship, choice order of schools, and computerised balloting. This is a departure from the T-score era, where decimal-point differences could decide a student's fate. Under AL scoring, more students share the same total score, which makes choice order — the sequence in which you list your six secondary school options — much more consequential than before.

MOE publishes indicative AL score ranges for each secondary school based on the previous year's posting exercise, giving parents a realistic benchmark when shortlisting schools. These indicative ranges are not guaranteed cut-off points but serve as a reliable reference. Parents should use them alongside open house visits, school programmes, and their child's interests to build a balanced list of choices.

Subject-Based Banding and Full SBB

Singapore is progressively rolling out Full Subject-Based Banding (Full SBB), which replaces the traditional Express, Normal (Academic), and Normal (Technical) streaming model with mixed-form classes. By 2024, most secondary schools had adopted Full SBB, meaning students take subjects at a level suited to their ability in each subject, rather than being locked into a single stream. A student posted through the Express posting group can still take Normal (Academic) level Mathematics if that better matches their aptitude, and vice versa.

This reform means the PSLE Score is now used to assign students to one of three Posting Groups (PG1, PG2, PG3, which broadly correspond to the old Normal (Technical), Normal (Academic), and Express streams respectively) for administrative purposes, but classroom learning is increasingly mixed. For parents, this changes how you evaluate secondary schools: a school's culture of differentiated learning and subject flexibility matters as much as its historical cut-off point.

How iWorld Learning Supports PSLE English Preparation

English is weighted equally with the other three subjects in the PSLE, yet it is the subject where consistent, skills-based practice yields the most reliable improvement in AL bands. At iWorld Learning, PSLE preparation focuses on the four tested components — Paper 1 (Writing), Paper 2 (Language Use and Comprehension), Paper 3 (Listening Comprehension), and Oral Communication — through small classes led by certified TESOL/TEFL teachers with extensive experience in Singapore's MOE syllabus requirements.

Our Primary School English courses follow CEFR-aligned learning paths tailored to each child's current ability, with targeted practice in situational writing, continuous writing, comprehension techniques, and oral examination strategies. Rather than rote drilling, the approach builds the underlying language competence that translates into real confidence in the exam hall — and real-world communication skills beyond it.

FAQ

When did Singapore change from T-score to the AL grading system?

The PSLE Achievement Level (AL) scoring system was introduced in 2021 for the Primary 6 cohort that sat the PSLE that year. The change was announced by MOE in 2016 to give schools and parents a five-year lead time to adjust.

What PSLE score is needed for the Express stream?

A PSLE Score of 20 or below qualifies a student for the Express posting group (PG3), though individual schools within the Express stream have their own indicative score ranges. A score of 22 or below also qualifies if the student has AL5 or better in all four subjects.

How do tie-breakers work when two students have the same PSLE Score?

When multiple students share the same PSLE Score and are competing for the last places in a school, MOE applies tie-breakers in this order: first, Singapore citizenship (citizens before permanent residents before international students); second, the order in which the student ranked the school among their six choices; and third, computerised balloting if all previous criteria are equal.

Can my child retake the PSLE to improve their AL score?

Retaking the PSLE is generally permitted only if there are exceptional medical or compassionate grounds approved by MOE. The PSLE is designed as a one-time national examination, so consistent preparation throughout Primary 5 and Primary 6 is the most practical strategy for achieving a desired AL score.

Does the AL grading system affect admission to Integrated Programme schools?

Yes. Integrated Programme (IP) schools admit students based on their total PSLE Score under the AL system, just like other secondary schools. IP schools typically require scores in the 4-to-9 range, although exact cut-off points vary by school and year. A strong performance in English, which counts as one of the four AL subjects, is often a distinguishing factor at this competitive end of the posting spectrum.

Summary

The PSLE AL grading system is a criterion-referenced scoring method that assigns each subject a band from AL1 (90+ marks) to AL8 (below 20 marks), with the total of four subjects forming the PSLE Score used for secondary school posting. Understanding AL bands, indicative score ranges, tie-breaker priorities, and the shift toward Full Subject-Based Banding helps parents make informed decisions about secondary school choices. English preparation plays a central role in achieving a strong overall score, and targeted support from experienced educators can make a meaningful difference in a child's confidence and performance.
